[Portaudio] Invalid number of channels...(?)
https://portaudio.music.columbia.narkive.com/rAVDzeQr/invalid-number-of-channels
Then I issue a Pa_OpenStream instruction, specifying that device as output, after having set the requested number of channels to 1 : outputParameters.channelCount = 1; /* mono output */ The Pa_OpenStream fails with error code -9998, which means : "Invalid number of channels" Is there a reasonable explanation for this behavior ? Thanks Alberto
